| Santiago de Cuba bay is an ecosystem eutrophic and vulnerable to FANs events. This work preset the results of monitoring during three year in eight stations located in the less polluted area of the bay, leading to the determination of the possible seasonal distribution and FANs frequency. 117 Phytoplankton species were identifying, which belong to 5 divisions; 28% of these species are reported as potentially toxic and/ or noxious. This zone of the bay classifies as politrophic, heterogeneous and dynamics. It highlights the cysts presence, as well as the occurrence of unialgal "blooms" of Gymnodinium catenatum and Cochlodinium polykrikoides, indicating the presence in the ecosystem of favorable conditions to HABs occurrence with negative impact on the... |

| During the expeditions Cimar - Fiordos 2, 3 and 4 (1996, 1997 and 1999), samples of marine sediments were collected in Southern Chile, between Melinka (Lat. 43° 45' S) and Beagle Channel (Lat. 54° 56' S) to study the distribution and abundance of dinoflagellate cysts, particularly the toxic dinoflagellate Alexandriurn catenella. Samples were collected from 33 stations at depths of 1 to 15 meters. The study included photographic record and taxonomic identification of cysts to genus and, whenever possible, to species, with emphasis on the identification of cysts of A. catenella. Cysts from samples collected in cruises 3 and 4, were incubated in f/2-Se culture medium at 13 °C with controlled photoperiod (14:10, L:D), to induce germination and confirm species... |
